To all whom it may concern." Be it known that 1, JOHN C. HnINE'Kn, a

Springfield, in the county of Sanga-mon 93nd State (if-Illinois, have invented certain new and useful Improvements in I oot Accelerators, of which the following-is a f's peciiication. I f

This invention relates to .footnccelerators commonly used. in connection with internal combustion engines es'used with motor 've hicles and the like. v "1 3 T'he purposes of thisinvention therefore, are first, to provide an economic. and simple means. or" controllingby foot pressure the .g'es feed of motor vehicles and the like.

' Afurther object oi' ny invention, is to provide an apparatus that has in its" construction provided. for .thejeliniinetion of ell loose motion in its n orniel operation.

V A further object of myi inven'tion is to provide adevice that may be easily, economically and quickly assembled and. attached to etteined by the -foot accelerator described in the annexed specificetion,;,recited in .the

claims and v illustrated. in the "accompanying drawings, in which like reference, nu-

I Thepreferred embodiment ofunyinvention is illustrated in the several figures .ab'ove nientioned'and the desired means 'of .operat- 6 ing this foot acceleratorf'will b1ej,cle:irly'funderstood by carefully observingth'efigures given with the instructions which follow'ior normally operating the-foot mammoth myinvention. y v 1 In vie'w'of. the factthet the-'niost common use for this invention i'wouldbe "in connection with the operation of motor vehicles; the manner of peration "willbe described .as

i When the driver of ammo-r vehicleldesires to increase the gasfeed forgth'e motor or accelerate the speed offthe vehicle, he presses his foot ontheg'pedal cap1 in'Fi'g. 1, his footjpressure isj'carried'tothe t rot 8 tle' of the vehicle centimeter illustrat at ment of the device liohmuyop r- 'ate' in their respective 'positionf;descr as follows: 'A foot pressure on cap lis' ibejd a? sh this pivot which is supported hy;brecket,-.5,

which is in turn fastened tothe-motor block. When the foot pressureiis'appliedmthe nor- 96. a pull 'to-be exerted on connecting rod 6 which is detachably secured to. slottedsleeve 8. which in turn a'ctuates the: throttle .10 1 of carburetor 11. It Wi1l -re.adily be observed that the foot pressure ofthe operator therefore causes the carburetor throttledstobe openiand thus increases the .fieedof lgasto the motor.

The normaljpdsitiong of -a.yc-arhuretor throttlehowever is; to. be closedet leastfto the limit ofclosure desired eyetee. rator which is set -by the optional pdjt t ne t of. the hand gas feed. lever usually i found on the steering-,wheel etinotor vehicleiifiln the normal operation of. thlsi oot eecele e ''manner described as follows:

; cotter pin 16 which is set into a hole drilled its normal action.

V pin 16 is secured and j mined position the operator whenever he desires as well as the foot acthrough the loose end of connecting rod 19..

This cotter pin therefore normally acts a stop for the 'niovem'ent of slotted sleeve 8 in It will be observed that when the pperator desires to set the hand control lever at a predeterminedlimit he adjusts l11S hand lever to the desired position and said adjustment is carried through red 15 and lever 12 connecting cotter pin 16 is thus optionally moved and set in' a predeterthereby determining the limit of movement for slotted sleeve 8.

In this connection it will be observed that is able to use the hand gas feed Ic'elera'tor.

Itlwill be observed that by usingthe V handlever, that the throttle is open through i as ing rod 9 is screwed into v sleeve 8 at 18, thus permitting a. longitudithe normal action'of connecting rod 19 in pulling cotter pin 16 back through the longitudinal slot in theslotted sleeveuntil it reaches the end of the slot and thus opens the throttle of the carburetor when the said cotter pin pulled against the end of said slot. p

It will be further observed. that a ball and socket-joint which is used to connect said slotted sleeve with connecting rod 6,

permits normal action of these two elements when in operation.

I It will be further observed that connectthe end of slotted n'al adjustment to be made if desired.

It is obvious that certain minor details in *the construction of my invention may be altered in their ,design and still stay within the-spirit and scope of my invention. For instance I do not wish to be limited to the design illustrated'of any one of the con ne'cting rods or the push-rod used in this invention, nor do I wish to be limited to the design of coil tensile spring illustrated in the drawing, as it is obvious other resilient means might be used for the purpose shown 7 and specified. Nor do I wish to be limited numeral 16 Fig. 2,

to'the cotter pin as a stop means shown at for the reason that it is obvious that other stopmeans equally effective might be used. I also wish not to be rod 19 towhich cotter limitedto the use of a ball and socket joint where such a joint is shown at numeral as it is obvious that other means of securing similar results may be used. It may be readily. observed that the manner or" operation of the invention herein described, provides for the elimination of lost motion in lever controls which is a very desirable merit for any'device of this character.

I call attention especially to the simple.

compact, firm and substantial manner in which the device of my invention is properly installed on a motor vehicle.

I call; further attention to' the neat, sub stantial and smooth manner in which longitudinally connecting rod 7 normally slide when actuated through the operators toot pressure.

Having thus described the nature of my invention, what I claim'as' new and useful and desire to secure by Letters Patent is:

1. A foot accelerator co-operatingwith a hand control for a motor carburetor and comprising'in combination a bracket supported bell-crank lever, controlled throttle 'rod connected with; a hand lever, a'telescopicall'y mounted longitudinally slotted tubular sleeve mounted on said hand control rod, means connecting said bell-crank lever with said sleeve, 'means for receiving and conveying foot pressure to' slotted sleeve 8 is mounted upon 19 on which it is adapted to Q0 7 a horizontalhand 7 said bell-crank lever, a tensile spring for automatically holding said bell-crank lever into normally closed position, and a rod connectingsaid sleeve with said carburetor as and for the purpose set forth.

2. An acceleratorincluding a foot lever i and pedal for conveying'foot pressure, a

throttle lever connected with carburetor, 1

a hand-lever and handcontrolled throttle rod, a tubular sleeve longitudinally slotted, slidably mountedfon said hand controlled throttle rod and adjustably connected with said first throttle lever at one end and slidably supported on said hand controlled throttle'rod at'the other end, stop means provided in a detachably secured cotter pin in the sleeve supporting end of said hand throttle rod adapted tomove within said longitudinal slot of said sleeve and limit the longitudinal movement thereof, and to pull against the'end of said slot in. the hand control of said carburetor, a bell-crank lever i connected with said foot lever'by one arm and supported by a motor mounted bracket, a ball and socket joint detachably secured to said sleeve at one end thereof, a connecting rod connecting the other arm of said bell-cranklever with said ball and socket joint, a tensile spring secured at one end to the bracket supporting said bell-crank lever and secured at the other end to said sec ond arm of said bell-crank lever and adapted to automatically retract said carb'uretor trolled throttle lever, a tubular sleeve telescopically mounted on saidhorizontally disposed hand controlled throttle lever, a longitudinal slot in said sleeve'to act as guide means for said sleeve, a connecting rod adjustably secured to said sleeve and connecting the same with said carburetor, means provided in a cotter pin in the end'of said hand controlled throttle rod for pulling against the end of said longitudinal slot in said sleeve when actuated by said hand lever in the normal opening by hand of said carburetor, means provided in a tensile spring mounted on a bell-crank lever for automatically closing said carburetor feed when hand lever is released; and having foot control elements including a foot pedal, a bellcrank lever and a ball and socket joint, a push rod connecting said pedal with said bell-crank lever, a bracket supporting said bell-crank leverrand secured to the side of a motor block, said ball and socket joint detachably secured to the aforesaid tubular sleeve, a connecting rod connecting one arm of said bell-crank lever With said ball and socket joint, the aforesaid spring adapted to also provide means for automatically holding said carburetor control in normally closed position after being actuated byhfoot pressure in opening said carburetor, thus providing means for independent action between said hand control and saidfoot con trol of carburetor.
